var io = require('socket.io').listen(app);

app.listen(8080);

// routing
app.get('/', function (req, res) {
  res.sendfile(__dirname + '/index.html');
});

// usernames which are currently connected to the chat
var usernames = {};

io.sockets.on('connection', function (socket) {

    // when the client emits 'sendchat', this listens and executes
    socket.on('sendchat', function (data) {
        // we tell the client to execute 'updatechat' with 2 parameters
        io.sockets.emit('updatechat', socket.username, data);
    });

    // when the client emits 'adduser', this listens and executes
    socket.on('adduser', function(username){
        // we store the username in the socket session for this client
        socket.username = username;
        // add the client's username to the global list
        usernames[username] = username;
        // echo to client they've connected
        socket.emit('updatechat', 'SERVER', 'you have connected');
        // echo globally (all clients) that a person has connected
        socket.broadcast.emit('updatechat', 'SERVER', username + ' has connected');
        // update the list of users in chat, client-side
        io.sockets.emit('updateusers', usernames);
    });

    // when the user disconnects.. perform this
    socket.on('disconnect', function(){
        // remove the username from global usernames list
        delete usernames[socket.username];
        // update list of users in chat, client-side
        io.sockets.emit('updateusers', usernames);
        // echo globally that this client has left
        socket.broadcast.emit('updatechat', 'SERVER', socket.username + ' has disconnected');
    });
});

and index.html

<script src="/socket.io/socket.io.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<script>
    var socket = io.connect('http://localhost:8080');

    // on connection to server, ask for user's name with an anonymous callback
    socket.on('connect', function(){
        // call the server-side function 'adduser' and send one parameter (value of prompt)
        socket.emit('adduser', prompt("What's your name?"));
    });

    // listener, whenever the server emits 'updatechat', this updates the chat body
    socket.on('updatechat', function (username, data) {
        $('#conversation').append('<b>'+username + ':</b> ' + data + '<br>');
    });

    // listener, whenever the server emits 'updateusers', this updates the username list
    socket.on('updateusers', function(data) {
        $('#users').empty();
        $.each(data, function(key, value) {
            $('#users').append('<div>' + key + '</div>');
        });
    });

    // on load of page
    $(function(){
        // when the client clicks SEND
        $('#datasend').click( function() {
            var message = $('#data').val();
            $('#data').val('');
            // tell server to execute 'sendchat' and send along one parameter
            socket.emit('sendchat', message);
        });

        // when the client hits ENTER on their keyboard
        $('#data').keypress(function(e) {
            if(e.which == 13) {
                $(this).blur();
                $('#datasend').focus().click();
            }
        });
    });

</script>
<div style="float:left;width:100px;border-right:1px solid black;height:300px;padding:10px;overflow:scroll-y;">
    <b>USERS</b>
    <div id="users"></div>

<div style="float:left;width:300px;height:250px;overflow:scroll-y;padding:10px;">
    <div id="conversation"></div>
    <input id="data" style="width:200px;" />
    <input type="button" id="datasend" value="send" />
</div>

Answer 1

Your question is very hard to understand, so Im not exactly sure what you are asking for, besides just general advice.

I did a quick search and found this Multiplayer HTML5, Node.js, Socket.IO

Might be helpful?
